Wow, talk about a stealth release. First released in 1998, Half-Life has never been available on OS X through Steam for Mac, even though every other Valve game — including Half-Life 2 and its episodic sequels — have. Sometime in the last few hours, though, Valve quietly released Half-Life for Mac on Steam… and still hasn’t apparently officially announced it.
Half-Life is one of the most iconic FPS games out there, a shooter that has set the bar for excellence to this day with its incredible narrative of dimensional invaders infiltrating a top-secret nuclear facility in Arizona. It’s the game that made Valve’s fortunes, and an all-time classic, so it’s great to see it on the Mac after fifteen years.
What’s strange about the release is that the official Half-Life store page still lists it as Windows only, but I’ve verified that if you buy it, it will install and run on a modern Mac. Presumably, an official announcement will follow soon, but in the meantime, you can start making your way through the Black Mesa compound for just $9.99.
